The Nikon Creative Lighting System (CLS)
Nikon’s advanced Creative Lighting System (CLS) offers improved communication
between the camera and compatible flash units for improved flash photography.
Refer to the documentation provided with the flash unit for details.
❚❚ CLS-Compatible Flash Units
The camera can be used with the following CLS-compatible flash units:
• The SU-800 wireless speedlight commander: When mounted on a CLS-compatible
camera, the SU-800 can be used as a commander for remote SB-910, SB-900,
SB-800, SB-700, SB-600, or SB-R200 flash units in up to three groups.
The SU-800
itself is not equipped with a flash.

balance, the camera will automatically detect the filter and adjust white balance appropriately.
2 Wireless flash control is not available with the SB-400.

Speedlight commander.
4 m/ft, 20 °C (68 °F), SB-910, SB-900, SB-800, SB-700, and SB-600 at 35 mm zoom head position; SB-910,
SB-900, and SB-700 with standard illumination.
A Guide Number
To calculate the range of the flash at full power, divide the Guide Number by the aperture.
For example, at ISO 100 the SB-800 has a Guide Number of 38 m or 125 ft (35 mm zoom head
position); its range at an aperture of f/5.6 is 38÷5.6 or about 6.8 meters (or in feet,
125÷5.6=approximately 23 ft 7 in.).
For each twofold increase in ISO sensitivity, multiply the
Guide Number by the square root of two (approximately 1.4).
